10 | Pyrophoric solids | Not classified | - | - | - | - | Considered non-flammable because tellurium, which can be produced by burning tellurium (Te) in air, is a stable oxide existing in nature as a mineral (Chemical Dictionary, 1994). |
11 | Self-heating substances and mixtures | Not classified | - | - | - | - | Tellurium oxide is considered non-flammable because it is obtained by burning tellurium (Te) in air and it is a stable oxide occurring in nature as a mineral (tellurite) (Chemical Dictionary, 1994). |
12 | Substances and mixtures which, in contact with water, emit flammable gases | Not classified | - | - | - | - | Stable to water (insoluble, Lide (84th, 2003)) |
13 | Oxidizing liquids | Not applicable | - | - | - | - | Classified as "solid" according to GHS definition |
14 | Oxidizing solids | Classification not possible | - | - | - | - | Classification not possible due to lack of data, though being inorganic compounds containing oxygen |
15 | Organic peroxides | Not applicable | - | - | - | - | Not organic compounds |
16 | Corrosive to metals | Classification not possible | - | - | - | - | Test methods applicable to solid substances are not available |
Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified | - | - | - | - | Based on the rat LD50 (oral route) value of >5,000mg/kg (RTECS (2004)). |
1 | Acute toxicity (Dermal) | Classification not possible | - | - | - | - | No data available |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | - | Due to the fact that the substance is "solid" according to the GHS definition and inhalation of its gas is not expected. |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible | - | - | - | - | No data available |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible | - | - | - | - | No data available |
2 | Skin corrosion/irritation | Classification not possible | - | - | - | - | No data available |
3 | Serious eye damage/eye irritation | Classification not possible | - | - | - | - | No data available |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available |
4 | Skin sensitization | Classification not possible | - | - | - | - | No data available |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | No data available |
6 | Carcinogenicity | Classification not possible | - | - | - | - | No data available |
7 | Reproductive toxicity | Category 2 | Warning | H361: Suspected of damaging fertility or the unborn child |
P308+P313: IF exposed or concerned: Get medical advice/attention. P201: Obtain special instructions before use. P202: Do not handle until all safety precautions have been read and understood. P281: Use personal protective equipment as required. P405: Store locked up. P501: Dispose of contents/container to ... |
Based on the evidence of adverse effects on pup development (malformation and fetal death), described in RTECS (2006) (though no data are available regarding parental toxicity). | |
8 | Specific target organ toxicity - Single exposure | Classification not possible | - | - | - | - | Insufficient data available. Refer to "Tellurium" (ID_0236, CAS_13494-80-9). |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (nervous system) | Warning | H373: May cause damage to organs through prolonged or repeated exposure (nervous system) |
P260: Do not breathe dust/fume/gas/mist/vapours/spray. P314: Get medical advice/attention if you feel unwell. P501: Dispose of contents/container to ... |
Based on the evidence from animal studies including "effects on the parasympathetic nervous system, muscle contraction/twitching" (RTECS (2004)). The effects on experimental animals were observed at dosing levels within the guidance value ranges for Category 2. Refer to "Tellurium" (ID_0236, CAS_13494-80-9). | |
10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available |
Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Not classified | - | - | - | - | Since it was suggested that relevant toxicity is not indicated in the water solubility (6.7mg/L(Merck 13th, 2001)) of this substance, according to from 96-hour LC50>1000000microg/L of the fish (Fundulus Heteroclitus) (AQUIRE (2003)), it was classified into Not classified. |
11 | Hazardous to the aquatic environment (Long-term) | Category 4 | - | - | H413: May cause long lasting harmful effects to aquatic life |
P273: Avoid release to the environment. P501: Dispose of contents/container to ... |
Since although acute toxicity is not reported within the aqueous solubility concentrations, it was a metallic compound, and the underwater action was unknown, it was classified into Category 4. |
